incident ray are on the opposite sides of the normal. These three laws can all be derived from the reflection equation. Real image – In optics‚ a real image is a representation of an object (source) in which the perceived location is actually a point of convergence of the rays of light that make up the image. Virtual image - In optics‚ a virtual image is an image in which the outgoing rays from a point on the object always diverge. It will appear to converge in or behind the optical

PLANE AND SPHERICAL MIRRORS Velorie D. Baquiran‚ Phy13L/A3 veldbaquiran@gmail.com Abstract The main theme or idea for this study circles around optics‚ more particularly on the device such as the mirror. Since light has a dual nature‚ it can travel both like a particle and like that of a wave. As the light travels from a person’s eyes‚ images can be form as it is reflected by the mirror. Properties such as reflection‚ refraction‚ interference and diffraction is identified in this study. Mirrors

8th physics light reflection refraction eyes defect and dispersion The ray of light which falls on the mirror surface is called incident ray. The point at which the incident ray strikes the mirror is called the point of incidence. The ray of light which is sent back by the mirror is called the reflected ray. The ‘normal’ is a line drawn at right angles to the mirror surface at the point of incidence. The angle between incident ray and normal is called the angle of incidence. The angle between

Fiber Optic Connector Assembly The three fiber geometry parameters that have the greatest impact on splicing performance include the following: Cladding diameter—the outside diameter of the cladding glass region. core/clad concentricity (or core-to-cladding offset)—how well the core is centered in the cladding glass region fiber curl—the amount of curvature over a fixed length of fiber These parameters are determined and controlled during the fiber-manufacturing process. As fiber is cut and

LIGHT- REFLECTION AND REFRACTION 01. What are the various uses of concave mirrors? 02. What are the various sign conventions for reflection by spherical mirrors? 03. A convex mirror used for rear view on an automobile has a radius of curvature of 3m. If a bus is located at 5m from this mirror‚ find the position‚ nature and size of the image. 04. What are the various factors of refraction of light? 05. (a) Define Power of a Lens. Write its SI unit. (b) Find the focal length of a lens

Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light‚ sound and water waves. The law of reflection says that for specular reflection the angle at which the wave is incident on the surface equals the angle at which it is reflected. Mirrors exhibit specular reflection. In acoustics‚ reflection causes echoes and is used in sonar. In geology
